76 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1933 



Dr. Waldo L. Schmitt spent the first 6 weeks of the year at the 

 marine laboratory of the Carnegie Institution of Washington at Dry 

 Tortugas, Fla., in continuation of studies of the crustacean fauna of 

 the region. A comprehensive collection of marine invertebrates, 

 mainly crustaceans, was brought back. 



During the early part of the year Dr. Paul Bartsch continued 

 studies of Cerion colonies on the Florida Keys, with the financial 

 assistance of the Carnegie Institution of Washington. On his return 

 he collected mollusks on several mountain peaks of the southern 

 Alleghenies. 



Austin H. Clark made several trips to the region included in the 

 proposed Shenandoah National Park in furtherance of a project for 

 coordinating and extending knowledge of the biology of the area, in 

 cooperation with the National Park Service, the United States 

 Bureau of Public Roads, and the Virginia State Commission on Con- 

 servation and Development. 



In July and August 1932, J. R. SwaUen, assistant botanist in the 

 section of grasses, collected in Yucatan under a cooperative arrange- 

 ment between the United States Department of Agriculture, the 

 University of Michigan, and the Carnegie Institution of Washington, 

 in connection with a biological survey of the Mayan area. The col- 

 lection obtained, about 1,000 specimens, has increased the known 

 grass flora of the region by more than 50 percent. C. V. Morton, 

 aid in the division of plants, left in March for a 3-months' botanical 

 exploration in Oaxaca. Because of an unfavorable season and Mr. 

 Morton's illness, this work, which was conducted with the kind 

 assistance of Dr. Emil Makrinius, of Pochutla, had to be considerably 

 curtailed. The 2,000 specimens collected, however, will prove valu- 

 able, since they come from a region little represented in the National 

 Herbarium. 



During the summer of 1932, Prof. C. E. Burt, of Southwestern 

 College, Winfield, Kans., carried on field work in herpetology designed 

 to obtain series of turtles in the region of the upper reaches of the 

 Cumberland and Tennessee Rivers. The Museum has long needed 

 material from that portion of the Appalachian system. The trip, 

 made by automobile, was eminently successful and resulted in large 

 and important collections. 



During the Peary Memorial expedition to the west coast of Green- 

 land, under command of Capt. R. A. Bartlett, arranged by the Peary 

 family, Arthur D. Norcross, and friends. Captain Bartlett obtained 

 a large collection of marine invertebrates mostly from the vicinity 

 of Cape York, wliich with customary generosity he presented to the 

 Museum. 



W. G. Sheldon and Richard Borden, during July, August, and 

 September 1932, undertook a second expedition to the mountain
